[PATCH] drivers: pci: Fix flexible array usage

[Purva Yeshi <purvayeshi550@gmail.com>]

Fix warning detected by smatch tool:
Array of flexible structure occurs in 'pci_saved_state' struct

The warning occurs because struct pci_saved_state contains struct
pci_cap_saved_data cap[], where cap[] has a flexible array member (data[]).
Arrays of structures with flexible members are not allowed, leading to this
warning.

Replaced cap[] with a pointer (*cap), allowing dynamic memory allocation
instead of embedding an invalid array of flexible structures.
